Application October 7,

4 Claims.

The invention relates to means for applying or removing ropes, belts orthe like driving means to or from driving wheels, pulleys and the like.The invention while of general application defines a special utility inthe oil fields with particular reference to the application and removalof bull ropes to or from the bull wheels forming parts of the oil rigsin common use in such fields.

The application to and removal of bull ropes 0 from bull wheels in oilrigs at the present time involves considerable difficulty as well asdanger of loss of lives to the operators.

According to my invention the bull wheel, pulley or the like to whichthe rope, belt or other flexible transmitting device is to be applied orfrom which it is to be removed is equipped with one or more adjustableperipheral sections Where by the rope or the like is guided onto or offof the wheel as the same is revolved in the proper direction. Thisdevice is extremely simple to operate and eliminates the presentdangers.

The invention will be more readily understood by reference to theaccompanying drawings showing a specific adaptation of the invention tooil field apparatus but it is to be understood that such showing issimply for the purpose of illustration and not by way of limitation, thebroad features of the invention being of general use and application andadapted for use with pumps of all sorts and various forms of drivingmeans employing ropes, belts or the like of round, flat or V shape.

In the drawings:

Fig. 1 is a diagrammatic side view showing an oil rig including a bullwheel embodying my invention.

Fig. 2 is a detailed plan view showing a peripheral section of the bullwheel moved to a position to guide the rope off the wheel in onedirection.

Fig. 3 is a perspective view showing the rope being guided in theopposite direction.

Fig. 4 is an end view of the adjustable section of the bull wheel.

Fig. 5 is a plan view of the adjustable section, the ropes being removedfor the purpose of showing details of construction.

Fig. 6 is a section on line 66, Fig. 4.

Referring to the drawings in detail the reference numeral l0 denotes anoil well rig of any conventional type including a bull wheel I l whichis adapted to be operated by one or more ropes l2. According to myinvention the bull wheel includes an adjustable rope applying orremoving peripheral member l3 which forms part of the wheel 55 itselfand which serves to guide the ropes onto 1936, Serial No. 104,516

or off of the wheel when moved to the proper position to the right orleft, while in the central position the adjustable section forms acontinuation of the periphery of the wheel and allows the rope tooperate in the usual manner.

Various adjusting means may be employed in connection with this device,one of which will be described in detail for the purpose of illustrationby reference particularly to Figs. 2 to 6 of the drawings.

As best shown in Fig. 4, a plate M in the form of a chord extendspart-way between two spokes of the wheel and may be welded or otherwisesecured to the wheel as indicated at l5. From this plate are pivotallymounted one or more arcuate guide members 16 by means of bolts or thelike ll extending through the plate. These adjustable members iii are soformed as to provide grooves 18 between adjacent members which grooves,when the peripheral members 16 are in working position, are in alignmentwith corresponding grooves E9 on the stationary portion of the bullwheel. It will be understood that the bull wheel may be provided withany desired number of such grooves and that the grooves may be of anysuitable shape to receive round, flat or V shaped driving ropes, beltsor other flexible members.

To permit adjustment of the arcuate groove carrying members IS, asliding plane Ell is provided, adjustably mounted in the fixed plate Hi.As shown three holes El are provided in the sliding plate any one ofwhich is adapted to be engaged by a spring-pressed plunger 22 extendingthrough the fixed plate [4.

The front ends of the arcuate members I6 are mounted to move with theslidable plate or bar 2|] by means of a suitable pin and slot connection23, 24.

In operation the sliding plate 20 may be adjusted in any .one of threepositions according to the hole which the spring-pressed plunger 22engages. When in the central hole as indicated in Fig. 6 the arcuatemembers it; are in such position that the grooves it formed between themare in alignment with the grooves on the stationary portion of the bullwheel. Assuming that the adjustable members are in this central positionthe bull wheel is adapted to operate in the usual manner and the bullrope or ropes will be held in position by the grooves l8 and [9. Toremove the bull rope from the wheel the shifting bar or plate 20 may bemoved either to the right or to the left and held in such adjustedposition by the spring plunger engaging with a proper hole 21 in thebottom of the adjustable plate. The bull wheel being now revolved in theproper direction the rope will gradually unwind itself from the bullwheel.

Similar operation will sufiice to apply the rope to the wheel, the wheelbeing of course rotated in the opposite direction from which it isrotated to remove the rope. It will be apparent that the entireoperation will be simple, smooth and effective and will result in amarked saving of expense and time and loss of life.

The invention has been described in detail for the purpose ofillustration but it will be obvious that many variations andmodifications may be resorted to Without departing from the spirit ofthe invention, as will be apparent to those skilled in the art.

I claim:

1. In a device of the character described a grooved wheel having aperipheral grooved section adjustable for applying or removing a belt,rope or like flexible driving member.

2. In a device of the character described a grooved wheel having aperipheral grooved section adjustable for applying or removing a belt,rope or like flexible driving member, and means for selectivelyretaining said section in working position or in belt applying orremoving position.

3. In a device of the character described a grooved Wheel having aperipheral grooved section adjustable for applying or removing a belt,rope or like flexible driving member, and means for selectivelyretaining said section in working position or in belt applying orremoving position, said means including a retractible pin.

4. A grooved wheel, pulley or the like for use in an oil rig, said wheelhaving a peripheral grooved section adjustable for applying or removinga belt, rope or the like, and means for retaining said section inworking position or in right or left belt applying and removingpositions. 20
